1

Victoria’s monthly income is $1200 and her savings is $300. Find savings to expenses ratio.

Savings to expenses ratio is 1:3

Solution

Victoria's Income = $1200

Savings = $300

Expenses = 1200 - 300 = 900

∴ savings to expenses ratio = 300:900 = 1:3

Savings = $300

Expenses = 1200 - 300 = 900

∴ savings to expenses ratio = 300:900 = 1:3

2

Out of 168 students in a class, 56 are boys. Find boys to girls ratio.

Boys to girls ratio is 1:2

Solution

Total Number of students = 168

boys = 56

girls = 168 - 56 = 112

∴ Boys to girls ratio = 56:112 = 1:2

boys = 56

girls = 168 - 56 = 112

∴ Boys to girls ratio = 56:112 = 1:2

3

Length and breadth of a rectangular field are 234 feet and 72 feet respectively. Find the ratio of length to breadth of the field.

Length to breadth ratio is 13:4

Solution

Length of a rectangular field = 234

breadth of a rectangular field = 72

∴ Length to breadth ratio = 234:72 = 13:4

breadth of a rectangular field = 72

∴ Length to breadth ratio = 234:72 = 13:4

4

Out of 105 students in a class, 7 prefer football, 49 prefer baseball and remaining like tennis. Find the ratio of number of students who prefer football to number of students who prefer tennis.

Number of students who prefer football to number of students who prefer tennis ratio is 1:7

Solution

Total Number of students = 105

Number of students prefer football = 7

Number of students prefer baseball = 49

Number of students prefer tennis =105 - (7 + 49) = 49

∴ Number of students who prefer football to number of students who prefer tennis ratio = 7:49 = 1:7

Number of students prefer football = 7

Number of students prefer baseball = 49

Number of students prefer tennis =105 - (7 + 49) = 49

∴ Number of students who prefer football to number of students who prefer tennis ratio = 7:49 = 1:7

5

There are 150 teachers in a school of 2925 students. Find number of teachers to number of students ratio.

number of teachers to number of students ratio is 2:39

∴ Number of teachers to number of students ratio = 150:2925 = 2:39

Total Number of students = 2925

∴ Number of teachers to number of students ratio = 150:2925 = 2:39

6

Self employed = 13680 - 7520 = 6160

∴ Government employees to self-employed ratio = 7520:6160 = 94:77

Number of Government employees = $7520

Self employed = 13680 - 7520 = 6160

∴ Government employees to self-employed ratio = 7520:6160 = 94:77
